This book is artfully and beautifully written. The story really doesn't have a beginning because it starts at the end, and Mr Kemp has well and truly mastered the art of segueing back and forward in the tale of the two main characters. The story centres around Tom, or Bobby Brown to his peers, who is already dead, and his twin sister Alice, or Alicia in her newly reinvented life. it traces the way their lives have travelled in two opposite directions, even though their paths often cross inadvertently through their separate social contacts. The plot twists and turns, moves forwards and back in time, and introduces new characters as others meet untimely demises. This is underground London at its finest, and the story is told in alarming detail. The research is extensive and anyone who has lived in the city will identify with the streets and places mentioned. I had no pre-conceived ideas about this book, but I thoroughly enjoyed it. Mr Kemp is a masterful story teller and I can't wait to see what he delivers next! A thoroughly deserved five stars.
